OIL BURNER.

Application led May 4,

The present invention relates to oil burners, and its particular object is to provide a very simple unitary structure coinbining a charge forming device with the burner proper.

My device is particularly intended to be used in connection With light oils, distillate and coal oil, but may be found useful for burning of hydro-carbons of any kind.

It is particularly proposed in the present invention to provide a body of oil, preferably heating the saine to a moderate temperature, and to discharge air under very inoderate pressure against the top surface thereof, and to allow the air which thus becomes saturated with oil vapors to pass through sinall orilices in the top of an enclosing vessel where it may be ignited to forni the burner llame, all of which features are coinbined in one unitary structure.

It is further proposed to allow the .saine principle to be used in connection with a plurality of individual burner tips, all of which receive their respective charges from 25 a common charge forming device.

It is further proposed to provide burner features particularly adapted to be used in connection with my burner.

Further objects and advantages of niy device Will appear as the specification proceeds.

The preferred forms of my burner are illustrated in the accompanying drawing, in which Figure l shows a vertical section through my burner. l i

` Figure 2 a fragmentary side view of a portion thereof.

Figure 4 a vertical section through a modified form of burner tip.

Figure 5 a vertical section through a further modified form of burner tip, and

Figure 6 a vertical section through a inodified charge forming device adapted to. be connected with a plurality of burner tips.

While I have shown only the preferred forms of the invention, I Wish to have it understood that various changes or modifi-` 5 cations may be made within the scopeof the claims hereto attached without departing from the spirit of the invention.

In its preferred form my burner lconsists of a c lindrical vessel 2 having a drain hole 3I at t e bottom adapted to be plugged 1925. Serial No. 27,943.A

by the screw 4 and surrounded in its body portion by an electric heater 5, the heating element of which is connected to the terminals 6. Oil is admitted into this vessel through the opening 7 which connects with a device, well known in the market and therefore not shown, adapted to maintain the oil in the vessel at a constant level as shown at S. ,A pipe 9 leads into the vessel above the normal oil level and has its eX- treinity bent downwardly as shownat 11, so that an air current passed through this pipe strikes the surface of the oil and then rises toward the top of the vessel after havivng become impregnated with oil vapors. 1n this connection, it inight be stated that the oil is heated by ineaiis of theheating eleinent to a moderate temperature only and that air is discharged through the pipe 9 under moderate pressure, any ordinary fan being` suitable for this purpose. In the form shown in Figure 1, the vessel is provided with a cap 12 having a flange 13 surrounding the upper portion of the vessel and formed with perforations 14 registering with perforations 16 in the upper end of the vessel. rlhe flange 13 is spaced from the upper end of the vessel in the manner shown in Figure 1, and a screen 17 is interposed between tlie flange and the vessel to prevent back firing. Heating of the oil by rmeans of the heat-ing element is required for starting only, since afterwards heat is transinitted to the whole vessel from the burner fraine. The vessel may be supported by any suitable means as by the lugs 18 eXtend ing radially therefrom which may be bolted to any suitable support.

ln Figure 4 is shown a somewhat different cap for the vessel, no perforations being provided in the upper end of the vessel nor in the flange of the cap, but slanting orifices 21 being formed at the edge of the cap which latter is cut on a slant as shown at 22 so that the charge escapes around the rim of the cap and may be ignited on the outside thereof. A screen 23 may be secured to the underface of the cap sok as to cover the orifices 21.

In Figure 5 is shown a still vfurther inodif secured to the central portion thereof as shown at 28, but recessed peripherally so that its outer portion is spaced from the cap to allow the charge to escape between the dislr and the cap and to be discharged circumferentially from the cap. The cap itself may be provided with a circumferential ridge Q8 narrowing the opening at the rim.

In the form shown in Figure (3, the vessel 2l in which oil is preferably maintained to the level indicated at 32 through the pipe 33 is surrounded by a second vessel 34 adapted to be filled with water to any desired height and provided with heating elements 36 in the bottom thereof whereby the water may be heated. Air currents are discharged against the surface of the oil through the pi 3e 87 which extends through the tops of both vessels and after having become saturated they rise through the pipe 38 from which they may be distributed to a plurality of burners not shown in the drawing'. The temperature within the outer vessel may be regulated by means of an automatic control shown on top of the vessel and including a diaphragm 39 disposed so as to be subject to the pressure within the outer vessel, the diaphragm having a pin lll secured to the inner end thereof which operates the movable contact #l2 of a switch t3 included in the circuit of the electric heater. It will be seen that in principle this device does not differ from that shown in Figure l and that combustible gases are generated in the same manner, that is, by means of the discharge of an air current against the top surface of4 a heated body of oil.

Particular attention may be called to one feature which allows the character of the mixture to be regulated. As a general rule, the mixture should be kept lean, but the character of the mixture is influenced by the level of the oil, that is, the higher the level of the oil, the richer will bethe mixture, and the lower the level of the oil, the leaner will be the mixture. Where" oil is fed into the burner from what is known as a siphon tank in which a constant level is maintainedI` the level of the oil in the burner may be easily changed by raising or lowering the burner itself. lVhere the burner is associated with a stove, it may be held in spaced relation to the supporting element so as to render the burner independent of the stove heat and to provide draft for combustion.

I claim:

l. A vaporizing apparatus of the character described, comprising a vessel partly filled with oil and having an oil inlet passage and a vapor outlet passage, a second fluid-tight vessel surrounding the same, partly filled with water, in which the first named vessel is wholly immersed, means for heating the water, pressure-operated means for cutting olf the heat when the water has attained a predetermined temperature, said means being wholly exposed to the interior of the second chamber, and means for discharging air under pressure against the surface of the oil allowing the air to absorb vapors from the oil and to` rise with thc same through the vapor outlet passage.

2. A vaporizing apparatus ot' the character described, comprising a vessel partly filled with oil and having an oil inlet passage and a vapor outlet passage disposed opposite to thc oil inlet passage, a second fluid-tight vessel surrounding the same partly iilled with water, in which the first named receptacle is wholly immersed, elec tric means for heating the water including an electric circuit, a switch therein, a diaphragni mounted so as to `be responsive to the pressure within the second vessel and connected to operate the switch for contr0lling the temperature within the second vessel and means for discharging air under pressure against the surface of the oil, allowing the air to absorb vapors from the oil and t0 be discharged through the vapor outlet passage.

3. A vaporizing apparatus of the class described comprising a fluid tight outer vessel filled with water, an inner vessel wholly disposed wit-hout the 'outer vessel and wholly immersed within the water, said inner vessel being partly filled with oil and having an oil inlet passage extending through the outer vessel together with a vapor outlet passage and an air inlet passage disposed opposite to the oil inlet passage and extending through the outer vessel and disposed above the level of the oil said outer vessel having a fluid tight compartment, an electric heater disposed therein, a diaphragm wholly disposed within the interior of the outer receptacle and responsive to the action of steam pressure generated therein, and an electric switch for controlling the current through the heater and operable by the diaphravm.
